摘要: Abstract: This paper presents new insights into the cause of regional geohazards from the Chi-Chi earthquake and typhoon events in the Da-Chia river watershed located in central Taiwan. To explore the coupling between the Chi-Chi earthquake and sequential geohazards in the Da-Chia river watershed, analyses of rainfall characteristics, rainfall-induced landslides, and debris flow formation from rainfall-induced landslides were conducted. Our findings indicate that the regional geohazards in the Da-Chia river watershed were mainly caused by the huge amount of sparsely deposited materials from landslides occurred by the Chi-Chi earthquake. Rapidly increasing water pressure caused by typhoon events with specific rainfall intensity provided a powerful force that moved the sparsely deposited materials into gullies and then triggered the debris flow movement. Furthermore, results obtained from the spatial distribution of rainfall in the study region demonstrate that the regional debris flow hazards in the Da-Chia river watershed are strongly related to the spatial distribution of rainfalls.
